Your right to resell your own stuff is in peril

At issue in Kirtsaeng v. John Wiley & Sons is the first-sale doctrine in copyright law, which allows you to buy and then sell things like electronics, books, artwork and furniture, as well as CDs and DVDs, without getting permission from the copyright holder of those products. Under the doctrine, which the Supreme Court has recognized since 1908, you can resell your stuff without worry because the copyright holder only had control over the first sale. That’s being challenged now for products that are made abroad, and if the Supreme Court upholds an appellate court ruling, it would mean that the copyright holders of anything you own that has been made in China, Japan or Europe, for example, would have to give you permission to sell it.
